It seems to be a bulletin board given, run a thread about something remotely technical for long enough and it will deteriorate into an old car discussion LO!
The worst of British. ![]()
That very much depends on the personal perspective of the person doing the reading LOL!
I know that youâre itching tell us about your memories of old cars. Donât be coy ![]()

Cars! Oh no! Theyâre tools. A exceptionally dangerous and expensive ones. Letâs talk about something more interesting. Erm, hammers. Letâs chat about hammers! ![]()

Dangerous? My field was industrial power electronics up to 11,000 Volts - now thatâs dangerous !!
Especially if you hit them with a hammer. ![]()
Or with an Ammeter !
Boom, boom. Possibly quite literally, Bes. ![]()
Proper motors JOCâŠ
They can practically drive themselves just latelyâŠWait a minute⊠![]()
Ha Ha, when I worked in the power industry 11kv was about where our voltages started.
Yes, indeed. And it is a serious matter for us and it can be just one mistake. That one mistake almost caused the death of a friend. It was in a paper mill where he mistook one section for another and he got electrocuted - 700 Volts DC. He survived but was in hospital for nearly a year.
When ah were tâlad, we used to hang fire elements down from tâoverhead pylon cables to cook roadkill ratsâŠ. Luxury, ladâŠ
How the hell can one survive 700V?? I assume tiny current?
My mate jumped off a haystack and tried to grasp an 1100 volt overhead cable.
It blew off two fingers and several toesâŠ
He turned into a good engineer when he was olderâŠThatâs when I worked with him.
Jeeez. Thatâs bonkers. Why would he do that? I used to bottle out of getting up to the bumps on a swing and leaping off at the top. Some people are fearless!!
Not me!
We had a crazy here, he jumped off a train, and lost two toes, we kincked his stolen stash, live dangerously ![]()
It was one of the variable speed drives on a large paper machine so tiny it was not. I imagine he he touched only one hand and touched that fleetingly - I wasnât there at that time,
Depends where the current flows. It will damage any organ in its path but I guess arm to arm would be the worst because the heart is in the middle.
Even minor electrical shocks can do damage that is not apparent until later.
Personally I have only known one person who died and that was due to a failure of procedure when a boilermaker removed a cover of a precipitator, sat down and dangled his feet in to wait for his paper work, it had just been livened up and he received 100s of thousand of volts DC. (the actual failure is a much longer story)
BTW DC is the worst because it doesnât allow you to let go (mind you that might be the least of your worries).
Have seen a few ashen faced colleagues who, for example, inserted a circuit breaker where the earth bar had snapped off in situ. When the site was inspected the surrounds of the breaker had metre long scorch marks where flames had erupted. He was fine, just scared shitless from being in the centre of a firestorm.
I have been showered with molten metal (well, very close to me) when a circuit breaker failed and the only way to isolate it was to open an Isolator (not designed to be opened on load) - I was wearing a lot of thick leather protective clothing from the boiler maker shop ![]()
